Application :filed October 2, 1913. Serial No. 793,042.

To all 107mm it may 'concern v Be it known that I, DAVID DoRN, a citizen of the United States, residing at St. Cloud, in the county of Stearns and Sta-te of Mm nesota, have invented a new and useful Grain-Shocker, of which the following is a specification.

r)This invention relates to machines for forming shocks from bundles of grain, one of the objects of the invention being to pro vide a machine of this character which can move forwardly in any desired manner and on which the bundles, when placed by any suitable means,will be arranged in parallel rows leaning toward each other, there being means for depositing the bundles, While in this position, upon the ground where they will remain standing in the form of a shock, the machine being so constructed as to automatically cease operating during the discharge of the shock onto the ground and to automatically reset so as to continue to operate as before, after the shock has been depositcd on the ground.

Another object is to provide improved means for placing the bundles on end in position to be engaged by conveying means adapted to carry the bundles into the shock former.

A further object is to provide a shock former including parallel compartments, the walls of which converge upwardly, there being a switch of novel form for directing the bundles into the two compartments successively.

Another object is to provide improved means for automatically stopping the feeding of bundles into the shock former while a shock is being discharged from the former.

A further object is to provide means for rendering the bundle feeding means of the shock former inactive during the discharge of the shocks.

A further object is to provide means operated by one of the bundles of the shock for automatically tripping the shock former so as to discharge the shock upon the ground.

lll/*ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it `being understood that changes in the precise embodiment of the invention-herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

Referring to the figures by characters of references 1 designate a frame adapted to be connected to one side of a binder so as to move therewith, this frame being provided, at its front end, with a platform 2 and, at one side of the front portion thereof, with a deck 3 on which the bundles from the binder are adapted to be placed. Platform 2 has upstanding side walls 4 converging forwardly, one of these side walls4 being curved at its front end so as to extend around the front end of the other side wall 4, as shown at 5, thus to form la curved passage G leading from the front end of the deck 3 around to the front portion of the platform 2. As shown in the drawings the upper ends of the walls of the platform can be connected by a top 7 and the deck 3 can also be provided with a housing 8. As shown particularly in Fig. 9, the bottom of thedeck is inclined downwardly toward the near wall 4 of the platform 2. Frame 1 is provided with parallelrearwardly extending sidev strips 9 the inner faces of which constitute backings for chains hereinafter referred to these strips being rigidly mounted in any suitable manner as by means of arches 10.

Hingedly connected to the rear yend of platform 2 is the bottom 11 of the shock former, this bottom being formed with a central upstanding core 12 the sides of which converge upwardly as shown at 13 and in planes parallel with the inner faces of the walls 9 a lip 11 is extended upwardly along each'side edge of the bottom. The rear end portion of the core 12 is carried by a toothed wheel 14 designed to rotate on the ground and which is secured to a lshaft 14', journaled in the core 12 and provided with a sprocket 15 for the purposehereinafter set forth. The core 12 is hollow and the frame 1 has an extension 16 extending rearwardly therefrom and under the hollow core, there being a yoke 17 mounted for rotation upon' the rear end n portion of this frame extension and normally extending upwardly and. forwardly, the upper end of the yoke being pivotally connected to the intermediate portion of a crank-shaped hanger 18, the ends of which are journaled within the sides of the core 12. .A rack bar 19 is pivotally connected to the intermediate portion of the hanger 18 and extends forwardly withinthe core and above a gear 20 which is keyed or otherwise secured to a transverse shaft 21 extending under the frame 1 and supporting the same, this shaft being also connected to a supporting wheel 22 located under the center of the rear end portion of platform 2 as will be Vapparent by referring to Figs. 2V and 9. Hangers 23 extend from the arches 10 down through the open top of core 12 to frame 1.

It has been found that the bottom 11 of the shock former can be hingedly connected to the front portion of the machine in a simple manner by utili-,zing the transverse shaft 21 as an axis about which said bottom can swing, as shown in Fig. 4.

Fixedly secured to the frame 1 back of gear 2O isa longitudinally slotted guide block 24 to one side of which is pivotally connected a shifting cam 25 having an arcuate slot 26, this cam being pivotally connected, as at 27, to one side of block 24 while a connecting rod 28 is pivotally connected to an arm 29 extending from the casting, the point of connection being indicated at 30. Actuating rod 28 extends rearwardly from the casting and within the hollow core 12, its rear end being pivotally connected to a. lever 31 mounted to work in a. substantially horizontal plane and pivotally mounted, as at 32 close to the center of the core 12. The outer end portion of this lever 31 projects through a slot 33 in the core and has an arm 34 extending rearwardly at an acute angle from the lever 31. A. spring is connected to lever 31 and to one wall of the core and serves to hold the lever nor mally pressed against the front end of slot 33 and the arm 34 normally extended obliquely across one of the compartments 3G formed at the sides of the core 12. Pivotally connected to the outer end portion of lever 31 and close to the core 12 is a trip 37 having a foot 38 adapted to bear against a backing block 39 which is located in the core and above the path of movement of lever 31. lThe trip 37 normally extends almost entirely across the compartment 36. It will be understood that when the trip 37 is pushed rearwardly by a bundle, the block 39 will prevent it from swinging inwardly toward the core 12 until after the foot 38 has passed the block 39 whereupon said foot will swing laterally in the slot 33 and trip 37 will swing against the side of core 12, as indicated by dotted lines in Fig. 8. rlhe arm 34 will, during this movement, swing inwardly against the wall of core 12 as shown in Fig. 8.

The arcuate slot 26 in the casting 25 rceeives a pin 40 which extends laterally from a slide 41, this slide being held to the guide block 24 by guide bolts 42 or the like extending through a slot 43 in slide 41. Slide 41 is also provided with a larger slot 44. The rack bar 19 bears downwardly on slide 41 and extending loosely through the slot 44 and bearing upon the bottom portion of slide 41 is a push bar 45, the upper end of which is loosely mounted on the rack bar 19 and is adapted to press against a pin 4G extending laterally from the rack bar 19. The lower end of the push bar extends through the guide block 24 and has a tooth or projection 47 which is normally spaced from gear 20 and is adapted to be brought into engagement with the gear when slide 41 is raised by the casting 25.

It will be understood from the foregoing that when the trip 37 is pushed rearwardly,

lever 31 is actuated so as to pull on rod 28 and this, in turn, will pull on arm 29 and cause the slotted portion 26 of casting 25 to move upwardly, thus elevating slide 4l. This slide will promptly lift the rack bar 19 out of mesh with gear 20- and will throw 'the projection 47 into engagement with gear 20 so that the gear, while rotating, will push against bar and cause this bar to push the pin 46 and the elevated rack bar 19 rearwardly, thus throwing the upper end of the crank hanger 18 past its dead center', thereby causing the bottom of the shock former to swing downwardly, as indicated by dotted lines in Fig. 3. After the rack bar 19 has been pushed back its greatest distance by the bar 45, the teeth of gear 2O will slip past the projection 47 as will be seen by referring to the dotted position of the parts in Fig. 5, the parts being held in this position as long as there are any bundles pressing against the rearwardly extending arm 34 as will be hereinafter more fully described. Spring 35 serves to return the trip 37 and slide 4l until rack bar 19 is in mesh with gear 2O and the toe 47 is disengaged from gear 20 whereupon the rotation of gear 20 returns bar 19 and bar 45 to their initial p0- sitions.

Arranged upon each of the upstanding side walls 4 of the platform 2 close to the rear ends of thewalls are vertical shafts 48, each of which is provided near its lower end with a gear 49 constantly meshing with a gear 50 secured to the transverse shaft 21. lilach of these shafts has a sprocket 51 secured thereto and adapted to rotate therewith, this sprocket engaging and actuating a carrier chain 52. The carrier chains engage sprockets 53 and 5B respectively. These sprockets are mounted in the front end portions of the walls 4, sprocket 53 being loosely mounted while sprocket 58 constitutes a driving element as will be hereinafter described. The inner flight of each chain 52 works along the inner surface of the adjacent wall 4. lilach carrier chain has teeth 54 extending therefrom at regular intervals, each tooth being pivotally connected to the chain and provided with a foot 55 eX- tending in a direction opposite to that in which the tooth is moving and adapted to slide along the adjacent wall 4 while in active position. This wall has a longitudinal slot 56 therein beginning opposite the extension on a s vitch hereinafter mentioned and normally mounted in this slot is a hinge leaf 57 hingedly connected to one end of a backing plate 58. The other end of the backing plate is likewise connectedy to two links 59, the plate 58 being preferably formed with recesses 60 in which the links 59 are normally seated, the connections between links 59 and the wall 4 being indicated at 61 in Fig. l5. The plate 58 is connected to the angle portion 53 of an tshaped gate 64, this gate being pivotally connected as at 55 to a bracket or other structure extending from the wall 4. @bviously by pulling outwardly and forwardly upon the hinge leaf 57, said leaf will be caused to swing laterally away from the wall 4 and plate 58 will also be moved laterally out of the slot 5G, this plate pulling on the links 59 and causing them to swing laterally and to pull upon the angle portion of gate Said gate will thus swing laterally about its pivot 65 so that the active portion of the gate will be brought into position within slot 5G and at right angles to the wall 4 so as to prevent the movement of bundles along the wall and past the gate, as shown bv dotted lines in Fig. l5. u

A rod 66 connects the hinge leaf 57 to one arm of a bell crank lever 67, the other arm of this bell crank lever being connected by a rod G8 to a crank arm 69 extending from one end of a transverse shaft 70 journaled on the frame 1. This shaft 70 has an arm 71 between the ends thereof and which is connected, by a rod 72, to one side of the crank hanger 18. VThus it will be seen that when the bottom of the shock former is dropped for the purpose of discharging a. shock, the crank hanger 18 while moving rearwardly and downwardly will pull through rod 72 upon arm 71 and cause the crank arm G9 to pull, through the rods 68, upon the bell crank levers 67, thus pulling through rods G6 upon the hinge leaves 57 and causing plates 58 to move laterally out of slots 56 and the gates 64 to move to active positions across thepassages at the inlet ends of the compartments in the shock former. Obviously, therefore, should the chains 52 be operating while the plates 58 are out ofposition with-- in the slots 56, the feet 55 will swing through the slots and the teeth 54 will thus become inactive and will not pull the engaged bundles toward the closed gates 64 but will slip past the bundles thus leaving the same in position close to the gates but without moving into the shock former.

Each shaft 48 has a sprocket 73 loosely mounted thereon and provided with ahub 74 in the periphery of which are formed notches 75, such as shown in Fig. 19. A. collar 75 rotates with each shaft 48 and has dogs 77 pivotally connected thereto at diametrically opposed points, these dogs being normally inclined upwardly and outwardly so as not to engage the hub 74. A rod 7 8 is slidably mounted upon the outer side of each w all 4 and is provided, at its rear end, with an arcuate laterally extending linger 7 9 which is normally removed from the path of the rotating dogs 77. This rod has a laterally eX- tending pin in the path of the lower arm of the adjacent bell crank lever 67 so that,

. when said bell crank lever is shifted for the and thus shift rod 78 longitudinally, thereby bringing linger 79 into the path of the dogs 77 so that, as these dogs rotate they will be brought against the finger and be shifted inwardly thereby so as to engage the notches 75, thus coupling hub 74 and sprocket 7 8 to the rotating shaft .48. As soon as bell crank ,lever 67 moves back to its normal position, linger 79 moves away from the dogs 77 and they are promptly moved back out of the notches 75 by a fixed cam 81 so that sprocket 78 will cease to rotate with shaft 48 after making one revolution.

A tripping arm 82 is pivoted in a slot 88 in each wall 4 and has means for pushing against rod 78 as each bundle is dischargee onto the platform 2 and directed toward one of the compartments of the shock former. p

Each of the sprockets 78 which is normally loose on shaft 48, is engaged by a conveyer chain 88 extending rearwardly fromthe sprocket and engaging an idler sprocket 84 mounted npon the rear end portion of the adjacent rearwardly extending strip rThe inner flights of the chains 83 are arranged along the inner surface of the strips 9 and each chain has teeth 85 provided with feet 86 adapted to slide along the strip9 so as to hold the teeth 85 extended transversely of the adjacent compartment in the shock former during the rearward movement of the teeth while pressing a bundle longitudinally within the shock former.

lhile the teeth 54 carried by the outer flight of the chain 52 remote from the deck 3 are inactivepthe corresponding teeth of the other chain 52 are active. In other words, all of the teeth on the chain 52 nearest deck 8 are constantly active except while passing over slot 58 from which plate 58 has been withdrawn. rlhe teeth on this chain 52 travel close to the path of a bundle setting or placing device which, as shown particularly in Figs. 11 to 14 inclusive, is made up of a plate 87 hingedly connected to the deck 8 along a line parallel with the 4. v J. 1 I. L f! path of moiy ement of the outer ihght o1 the chain 52, this plate 87 being provided, along its lower or hinged end, with an outstanding ledge 88 mounted to swing independently of plate 87 and held normally at right angles .to said plate 87 by a spring 89. Ledge 88 has a latch 90 iixedly connected thereto and extending laterally therefrom beyond the hinge 91, this latch being provided with a beveled head 92 normally projecting through a slot 98 formed in an actuating arm 94. rllhis actuating arm is preferably forked as shown in F ig. 14 and is pivotally connected, at its upper end, to the upper portion of the back of plate 87. The lower end of arm 94 has an opening 95 through which extends a rod 96, this rod having a pin 97 at its free end for preventing withdrawal of the rod from the opening 95. A spring 98 is mounted on the rod and bears at one end against the pin 99 on said rod and at its other end against the apcrtured portion of arm 94. Rod 9G is pivotally connected by a pitman 101 to a crank arm 102 extending from the lower end of a vertical shaft 103. This shaft is actuated by the adjacent chain 52 which serves to rotate sprocket 58 keyed on shaft 108. .lt is to be understood that any other suitable means may be utilized for transmitting motion from shaft 103 to the bundle placer so that said placer will be elevated whenver a bundle is arranged thereon.

The rear portion of platform 2 has a partition 104 extending longitudinally of the center thereof and up to the front end of the core 12. This partition serves to divide the back of the space between the walls 4 into two throats 105 and 10G respectively, the throat 105 discharging into the chamber 86 in the shock former while the throat 106 discharges into the chamber 107 of the shock former and which is similar to the chamber 36. A V-shaped switch 108 extends from the front end of partition 104, its point being adapted to travel in an are from the front end of one wall 4 to the front end of the other wall 4. Arcuate wings 109 extend from the rear portion of the switch 108 and beyond opposite sides of the front end portion of partition 104, these wings being so proportion and shaped that, when the point of the switch 108 is bearing against one wall 4, one of the wings 109 is extending across the inlet end of the opposed throat 105 or 106.

rlllhe operation of the machine is as .follows z-During the forward movement of the machine shaft 21 is rotated by wheel 22 and motion is transmitted therefrom through the gears 50 and 49 to the shafts 48 which, in turn, continually drive the chains 52 in the directions indicated by the arrows in Fig. 1. Let it be assumed that the switch 108 is in the position indicated by full lines in Fig. 1 and that the bottom of the shock former is held in raised position. by thc crank hanger 18 being pulled fo1'\\'ardly past the dead center of the yoke 17, the forw rd moi ement of the rack bar 19 and the crank hanger 18 being limited by the crank coming against an arch or yoke 10 or in any other preferred manner. A projection 45 limits the movement of bar 45. The dogs 77 are normally out of engagement with the hubs 74 of sprockets 73 and, consequently, shafts i8 rotate ordinarily without transmitting motion to the chains 83. 11s the crank hanger 18 is extended in the manner stated, the rod 72, shaft 70 and rod 66 together with the various parts connected thereto, hold the plates 58 in closed position within the slots 56. @ne of the chains 52 constantly rotates the sha-ft 103 and, consequently, the crank arm 102 will continuously actuate the bell crank lever 100'so that the rod 96 will cause arm 94 to swing back and forth relative Ito the lowered placer plate 87, this being due to the fact that the latch 90 is out of engagement with arm 9-1 as long as ledge 88 is not weighted down. lililhen, however', a bundle is placed on the inclined plate 87 the weight thereof will cause the ledge 88 to swing downwardly so as to move the latch 90 upwardly at its free end. Thus, when the arm 9a is drawn against the plate 87 by the rod 96 during the actuation of crank arm 102, the head 92 of the latch will engage the slotted portion of arm 94 and thus automatically lock the arm against movement relative to plate 87. Consequently during the continued rotation of the shaft 103 and the actuation of bell crank lever 100, the rod 96 will push, through spring f chain 52 so that the teeth outstanding from said chain will engage the bundle and carry it into the passage 6, thence around through the pasage against the switch 10S which will deflect the bundle into throat 105. In passing through this throat the bundle will strike the trip or arm 82 so as to shift rod 78 longitudinally the linger 79 thus being brought into the path of the rotating dogs 77 and said dogs caused to couple sprocket to shaft i-8. Consequently chain 83 will be actuated until after the bundle has been placed on the shock formerat which time the bundle will be brought into position. to be engaged by one of the teeth 85. ln passing into throat 105, the bundle will engage the wing 109 thus shifting the switch to the position indicated by dotted lines in Fig. 1 whereupon the next time a bundle is directed through the passage 6 in the manner hereinbefore described, it'will be deflected into the throat 106. During this movement into the throat the bundle will strike the adj acent wing 109 and shift the switch 108 back to the position shown in full lines in Fig. 1 and the bundle will at the same time shift the adjacent trip or arm S2 so as to couple the other shaft 18 to the adjacent sprocket 73, thereby actuating the chain 83 for a short distance. rllhis operation will continue until chamber 107 has been filled and, as the last bundle of the shock is directed into the chamber 36, the first bundle will press against the trip 37 and cause it to swing rearwardly to the position indicated by dotted lines in Fig. 8, the arm 34 at the same time being swung inwardly against the wall of the core 12. Rod 28 will thus pull upon the elevating cam or casting 25 so as to shift slide l1 and elevate the rack bar 19 and the bar 45. Projection l7 will be brought into engagement with the rotating gear 20 and will be pushed upwardly and rearwardly thereby, thus causing the rack bar 19 to shift rearwardly and to throw the crank hanger 18 past its dead center, thereby permitting the whole shock former to drop to the ground at its rear end. During this action the rod 72 pulls through arm 71 so as to rotate shaft 70 and cause the crank arm 69 to pull on the rod 68. Thus the bell crank lever 67 will pull through rod 66 upon the hinge leaves 57, thereby causing the plates 5S to withdraw from slots 56 and causing the gates 611 to swing across the rear end of the throats 105 and 106. Consequently should any bundles be directed into either throat during the forward movement of the machine, while the shock is being deposited on the ground, the teeth 54 will not operate to shift the bundles into the chambers 36 or 107 and furthermore the gates 64 will opera-te positively to prevent any bundle from falling into either of the chambers 36 or 107. When the shock former is lower-d at its rear end in the manner olescribed, the bell crank levers 67 strike the projections 80 so as to shift the rods 7 8 longitudinally and thus cause the dogs 77 to engage the hubs 711; of sprockets 7 3, one of these dogs remaining constantly in active position so that the sprockets 73 will thus be.

rotated continuously with the shafts i8 as long as the bell crank levers 67 press against the projections 80. Vllherefore the chains 83 will operate continuously to force the bundles out of the chambers 36 and 107 during the forward movement of the machine, the bundles being left standing on end and the bundles leaving one of the chambers 36 being inclined upwardly toward and supported by the bundles leaving the other chamber 107. During this forward movement of the machine the bundles press the elongated arm 34 against the side of core 12 so that there is no danger of the lever 31 swinging back to its normal position under the action of spring 35. As soon as the last bundle has left'the chamber '36, which will be simultaneously with the removal of the last bundle from chamber 107, arm Slwill he released and, therefore, spring 35 will bring lever 31 back to its initial position and the trip 37 .and arm 3A; to their initial positions. At the same time lever 3l will press f' forward movement of the machine, it will draw the' rack bar 19 longitudinally, this movement continuing until the last tooth of the rack bar has passed out of mesh with gear 20, at which time the crank hanger 18 passes its dead center, the weight of the bottom of the shock former causing the crank hanger to swing forwardly and downwardly until projection 45 comes against the lower end of the slide 41. During this movement l the rod 7 2 rotates shaft 70 so as to cause the crank arms 69 to push through rods 63 against bell crank levers 67 so that the hinge leaves 57 and 59 and the plates 58 will be swung inwardly into the slots 56 and gates 64 willv be swung out of active positions.

Any bundles which may be standing in the throats 105 and 106 or within the passage 6 will thus be directed as before into the chambers of the shock former whereupon the operation hereinbefore described will be repeated. -By providing the springs V98 upon the rods 96, the bundles can be held in upstanding positions while shaft 103 is making a one half revolution, thus enabling the tooth engaging the bundle to move it into the passage before the placer is forced back to its original position. In order to prevent bundles from falling under the placer while vit is elevated, an arcuate shield 111 is vextended downwardly from the outer or upper edge of the placer, as shown in Figs. 11 and 12.

It will be noted that each of the compartments in the shock former at the sides of the Vcore 12 is overhung by an endless belt V112 extending longitudinally of the shock former, each belt being mounted on rolls 113 and 114, the rear rolls 114 being inclined downwardly and laterally so that the belt is givena twist. These rolls 113 and 114 can be mounted in any suitable manner and the sprocket 15 hereinbefore referred to is connected, by a chain 115, to a sprocket 116 secured to the shaft of the rolls 113. Thus it will be seen that when the toothed wheel 14 'is dropped into contact with the ground during the release of the shock, said wheel will be rotated and motion will be transmitted therefrom through chain 115 to rolls 113 so that the belts 112 will be driven inthe direction indicated by the arrow in Figs. l2 and 3, the lower flights of these belts engaging the tops of the bundles and causing them to move rearwardly away from the former while the core is being withdrawn from the shock. This discharging means thus operates to prevent the standing bundles from falling over during the withdrawal of the core.

It will be seen that when the machine is discharging a shock, the belt above the shock former will drop downwardly when the jointed supports are shifted as indicated by dotted lines in Fig. 3, thus causing the belt to force the bundles into the stubble, making a substantial shock.

Vhat is claimed is 1. The combination with a shock former having separate chambers, throats opening into the respective chambers, and a bundle actuated switch for closing the inlet end of either throat, of endless conveyers for directing bundles against and past the switch and into the respective throats to shift the switch, one of said conveyers constituting means for directing bundles to the switch, a shaft rotated by one of said conveyers, and means operated by said shaft for elevating a bundle against said bundle directing means.
